Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," and the like indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate description of the present utility model and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

Referring to fig. 1-5, the present utility model provides a technical solution: the anti-falling lifting hook comprises a hook body and an anti-falling mechanism, wherein the anti-falling mechanism is connected with the hook body 1 through a connecting piece 3; the anti-disengaging mechanism comprises an adjusting rod 5, a supporting rod 8 and a limiting rod 9; the supporting rod 8 is fixedly connected with the adjusting rod 5 and the limiting rod 9 respectively.

The upper end of the hook body 1 is provided with a bearing rod 2, one side of the connecting piece 3 is provided with a groove 4, and the bearing rod 2 is used for bearing the weight hung by the hook body 1.

A rotating shaft 7 matched with the groove 4 is welded at the end part of the adjusting rod 5, and a stop lever 6 is arranged at the other end part of the adjusting rod 5; the stop lever 6 can limit the adjusting lever 5 to lock the position of the supporting rod 8, so that the limit lever 9 is prevented from moving out of the position of one side of the hook tip of the hook body 1 due to the fact that the adjusting lever 5 continues to rotate.
